Right now I have it in 3.5 cubes sealed with about 1200 watts, but I would like to port it. Naturally, this sub has the potential to get loud at VERY low frequencies. The biggest dimensions I can have is 35" W x 16" H x 35" D. I'd like to keep the incredible musicality of this sub, and would just like to be louder. I LOVE the low end, but also would like the sub to play above 60hz. If I could make a box, (or have one made :)) that had a near flat response from 25hz to 50hz that would be ideal. Any suggestions? Thank you
